Hey Everyone, I’m down to 1 last error that I know I created on my own but I can’t figure out how to fix it… Here is the error that I’m getting: Apr 3 04:29:37 ip-172-31-24-2 postfix/qmgr[20458]: EFE01423E2: from=<me(a)spike.net>, size=359, nrcpt=1 (queue active) Apr 3 04:29:37 ip-172-31-24-2 dovecot: lda(beth(a)primelashdiva.info): Fatal: setresgid(89(postfix),89(postfix),97(dovecot)) failed with euid=97(dovecot): Operation not permitted Apr 3 04:29:37 ip-172-31-24-2 postfix/pipe[20745]: EFE01423E2: to=<beth(a)primelashdiva.info>, relay=dovecot, delay=22, delays=22/0.01/0/0.01, dsn=4.3.0, status=deferred (temporary failure) So I figure that I messed up the permissions on /etc/dovecot/conf.d I tried to fix it even by setting it way open: drwxrwxrwx 2 dovecot dovecot 4096 Mar 30 00:56 conf.d And it still doesn’t work! doveconf -n: $ doveconf -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 4.1.17-22.30.amzn1.x86_64 x86_64 ext4 auth_mechanisms = plain login first_valid_uid = 89 hostname = mail.primelashdiva.info mail_location = maildir:/var/vmail/%d/%n/Maildir mail_privileged_group = dovecot mbox_write_locks = fcntl namespace inbox { inbox = yes location = prefix = separator = . } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } postmaster_address = postmaster(a)primelashdiva.info protocols = imap lmtp service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = dovecot mode = 0666 user = dovecot } user = dovecot } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl = no ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem ssl_protocols = !SSLv2 !SSLv3 userdb { args = uid=postfix gid=postfix home=/var/mail/vhosts/%d/%n driver = static } protocol lmtp { mail_plugins = " sieve" } protocol lda { mail_plugins = } [ec2-user@ip-172-31-24-2 dovecot]$ It might be too late for me to concentrate enough to figure it, but my googling isn’t bringing up any info… Any pointers?

Problem with GSSAPI
by Luca Bertoncello 03 Apr '16

03 Apr '16

Hi list! I'm really puzzled... I have a Mailserver with Dovecot 2.2.9 (installed from Ubuntu 14.04-Repositories) and it works well with LDAP-Authentication agains the Active Directory. Now I want to use GSSAPI to allow the clients (with Thunderbird 38.7.1) to read E-Mails without giving a password. I configured Dovecot using these HowTos: http://mindref.blogspot.de/2011/02/dovecot-kerberos.html http://wiki.dovecot.org/Authentication/Kerberos But it does not work... In mail.log I can just see: Apr 3 09:52:26 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 3 09:52:26 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 3 09:52:26 mail dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libmech_gssapi.so Apr 3 09:52:26 mail dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 3 09:52:26 mail dovecot: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Apr 3 09:52:26 mail dovecot: auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Apr 3 09:52:26 mail dovecot: auth: Debug: auth client connected (pid=2300) Apr 3 09:52:26 mail dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.50.54, lip=192.168.50.3, session=<x8Sq5I8vsADAqDI2> and Thunderbird says that the Ticket was not accepted and I have to check if I'm logged into the Kerberos/GSSAPI subsystem. I checked with tcpdump and I see that Thunderbird does NOT send at all any request. Could someone help me? Thanks a lot! Luca Bertoncello (lucabert(a)lucabert.de)

Found 4 bugs in latest SquirrelMail related to IMAP and SMTP STARTTLS, Dovecot capabilities
by Tobias 03 Apr '16

03 Apr '16

This is a cross-post from the squirrelmail-devel list. It may be of interest if you want to run SquirrelMail and connect to Dovecot (and Postfix, possibly other servers) on a remote host using STARTTLS. BR Tobias -------- Forwarded Message -------- Subject: [SM-DEVEL] 4 bugs, IMAP and SMTP STARTTLS, Dovecot capabilities Date: Sun, 3 Apr 2016 04:27:56 +0200 From: Tobias <lists.zxinn(a)otaking.se> Reply-To: Squirrelmail Developers Mailing List <squirrelmail-devel(a)lists.sourceforge.net> To: squirrelmail-devel(a)lists.sourceforge.net Hello! I've looked for and have not seen any similar issues reported related to STARTTLS. Sourceforge wouldn't let me create an account or else I could have submitted bug reports directly. I'm using SquirrelMail 1.4.23 installed from latest FreeBSD Ports, together with PHP 5.6. I'm attempting to connect using STARTTLS to Dovecot 2.2.22 and Postfix 3.1.0. I've verified the code is not fixed for any of these four issues in the latest 1.5.2 SVN. Issue 2 is not as much of a problem in 1.5.2 as it is in 1.4.23 when using 'login' authentication. I connect to the IMAP and SMTP servers using their IP, but need to override the 'peer_name' to validate the certificate properly. New in PHP 5.6 is also that verify_peer defaults to TRUE, which means I need to either be able to set the peer_name, or disable verify_peer. I've found three issues in functions/imap_general.php, related to STARTTLS and Dovecot IMAP server, as well as one STARTTLS issue in class/deliver/Deliver_SMTP.class.php, class class Deliver_SMTP, function initStream. Issue 1: Stream options ($imap_stream_options) are not used with STARTTLS ($use_imap_tls = 2) in function sqimap_create_stream. The stream options are only used for $use_imap_tls = 1. How to fix: Add something like this: // set context options to allow for SSL option overrides @stream_context_set_option($imap_stream,$stream_options); Before trying to initiate the TLS session here: functions/imap_general.php :: function sqimap_create_stream 826: // start crypto on connection. suppress function errors. 827: if (@stream_socket_enable_crypto($imap_stream,true,STREAM_CRYPTO_METHOD_TLS_CLIENT)) { Issue 2: IMAP capabilities are only read once in function sqimap_create_stream (and subsequently used in sqimap_login to determine certain login options), however the capability list for Dovecot is not the same before and after STARTTLS. From Dovecot, before STARTTLS (telnet <local-ip> 143): * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED] Dovecot ready. From Dovecot, after successful STARTTLS (openssl s_client -starttls imap -connect <local-ip>:143): <SSL session info> --- . OK Pre-login capabilities listed, post-login capabilities have more. a capability * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN a OK Pre-login capabilities listed, post-login capabilities have more. How to fix: Issue "capability" command after successful STARTTLS to re-read the capabilities. Either as part of function sqimap_create_stream, or after call to sqimap_create_stream and before login options are checked in function sqimap_login. SquirrelMail 1.4.23 uses the return value with capabilities from function sqimap_create_stream to determine if 'login' is a viable option. Dovecot reports LOGINDISABLED prior to STARTTLS. (1.5.2 does not have this check for 'login'.) Issue 3: Multi-line response from the server to the AUTHENTICATE PLAIN (and likely cram/digest md5, possibly even login) are not accepted. The IMAP protocol allows the server to prefix responses which are incomplete with "*", and Dovecot uses this to report capabilities after successful login, but this is not handled by SquirrelMail's sqimap_login function. SquirrelMail reports: Unknown error: IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SEARCH=FUZZY SPECIAL-USE QUOTA The full output from Dovecot is: * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS THREAD=ORDEREDSUBJECT MULTIAPPEND URL-PARTIAL CATENATE UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS BINARY MOVE SEARCH=FUZZY SPECIAL-USE QUOTA A003 OK Logged in How to fix: Check if '*' is the first token in a response, and read another line from the stream. Possibly something similar to this: while (substr($read,0,1) == '*') { // OK so far.. $read = sqimap_fgets($imap_stream); } Issue 4: Identical to issue 1 but for SMTP. $use_smtp_tls = 2 and STARTTLS in class/deliver/Deliver_SMTP.class.php, class class Deliver_SMTP, function initStream, does not honor stream options.

Still muddling through with broken auth...

Hey Everyone, I’m still muddling through my first install… Followed the tutorials on workaround.org <http://workaround.org/> which were very helpful! but don’t include much info if things don’t work 100%… and so far I haven’t been able to pin down where the error is. When I try: telnet localhost 143 this is what shows up in the maillot: Apr 2 21:06:57 ip-172-31-24-2 dovecot: auth: Fatal: Unknown database driver 'sql' Apr 2 21:06:57 ip-172-31-24-2 dovecot: master: Error: service(auth): command startup failed, throttling for 2 secs Apr 2 21:06:57 ip-172-31-24-2 dovecot: imap-login: Disconnected: Auth process broken (disconnected before auth was ready, waited 0 secs): user=<>, rip=127.0.0.1, lip=127.0.0.1, secured, session=<+lw34IYvVgB/AAAB> With the failed driver for the database, I tried mysql and sql both of which produce the same error… I have a few other issues but I think those are related farther upstream… Not being able to sign into round cube for webmail, because of it being unable to connect to the storage container… But I think that’s a round cube issue… I want to get postfix and dovecot playing nicely before I worry too much about things like webmail access… Here is my postconf -n: [ec2-user@ip-172-31-24-2 dovecot]$ postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 html_directory = no inet_interfaces = localhost inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550 virtual_mailbox_domains = hash:/etc/postfix/virtual_mailbox_domains virtual_mailbox_maps = hash:/etc/postfix/virtual_mailbox_users virtual_transport = dovecot [ec2-user@ip-172-31-24-2 dovecot]$ What else can I provide?

SIS deduplication fails to create intermediate directories and funny permissions
by Jesus Cea 01 Apr '16

01 Apr '16

I have configured my system to use SIS, sharing the same same storage for all users, and offline deduplication. I have this in my "root" cron: """ 53 1 * * * /usr/local/bin/doveadm purge -A 16 * * * * /usr/local/bin/doveadm sis deduplicate /home/dovecot/buzones/attachments /home/dovecot/buzones/attachments/queue """ Yes, it is launched as "root" but I would expect doveadm drop privileges as soon as possible. This is working great, but from time to time I get this error message: """ Your "cron" job on babylon5 /usr/local/bin/doveadm sis deduplicate /home/dovecot/buzones/attachments /home/dovecot/buzones/attachments/queue produced the following output: Error: mkdir(/home/dovecot/buzones/attachments/dc/62/hashes) failed: No such file or directory """ Looks like doveadm is trying to create the "hashes" directory but the parent "62" doesn't exits yet. If I create that directory by hand and set permissions correctly, everything (seems to) work. Talking about this, I see something strange wit the permissions. All files and directories in SIS are created with "dovemail" user and group EXCEPT the "hashes" directory inside the newly created directory. That is: When I get the error message, I have this: """ drwx------ 7 dovemail dovemail 7 Apr 1 13:28 . drwx------ 237 dovemail dovemail 237 Mar 24 20:09 .. drwx------ 3 dovemail dovemail 3 Feb 29 02:30 1d drwx------ 3 dovemail dovemail 3 Mar 9 01:53 7f drwx------ 3 dovemail dovemail 3 Feb 29 02:30 88 drwx------ 3 dovemail dovemail 3 Feb 29 02:30 8d """ I create the missing directory by hand and change permissions.

default namespace

Hello, With no namespace settings and dovecot 2.0.9 I get the following listing: a LIST "" "*" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "INBOX" a OK List completed. Then I add the namespaces: namespace inbox { separator = . prefix = inbox = yes hidden = no list = yes subscriptions = yes } namespace compat { separator = . prefix = INBOX. inbox = no hidden = yes list = no alias_for = } Then list output changes: a LIST "" "*" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasChildren) "." "INBOX" a OK List completed. INBOX now has \HasChildren, while before it had \HasNoChildren. How can I make it \HasNoChildren?

Multiple IMAP Mailboxes and one collection folder
by Dieter Knopf 31 Mar '16

31 Mar '16

Hello, we use many IMAP folders and now we are searching for a way to display all mails inside this folders in one collecting folder. The advantage for us would be the possibility to view all new incoming mails in one folder. It would be possible to use the standard MAIL App on the iOS without problems. I could simply make a copy of all mails in one folder with Sieve, but then the Per-user Seen Flag would be useless, because the mail inside the folder is still unread. Is there a way to show some way of collecting folder for every user? Thanks Dieter

Dovecot plugin pthread issue
by qmail＠top-consulting.net 31 Mar '16

31 Mar '16

I am using FreeBSD 10.1 and Dovecot 2.2.22 with the Openchange plugin - https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu… (https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu…) The plugin compiles just fine and works up until when it tries to create a socket using nanomsg, which uses a pthread_create() call. At that point dovecot-lda just hangs indefinitely. I've read that -pthread must be included in all the components that might end up using it. So checking with ldd: nanomsg does include libthr ( pthread equivalent in FreeBSD ) openchange plugin also includes libthr dovecot-lda doesn't include libthr Would dovecot-lda also need to be compiled with -pthread ? Is it safe ? How can it be done ? Thank you!

Dovecot-LMTP and LDAP: passdb doesn't support credential lookups
by Niols 30 Mar '16

30 Mar '16

Hello, Sorry, this might be a newbish question, but I really can't get the answer by myself. I'm trying to setup a mail server using LDAP to authenticate users, and I keep receiving the errors: passdb doesn't support credential lookups passdb doesn't support lookups, can't verify user's existence when I send test mails to (existing) users. I'm already using the LDAP server for other purposes, and it's working fine. I can't (or I don't want to) give read access to the userPassword attribute, so I want to use a authentication bind: http://wiki.dovecot.org/AuthDatabase/LDAP/AuthBinds I've already managed to have postfix working with this LDAP server, the users (and their aliases) are correctly recognized. Postfix then sends the mails to Dovecot (2.2.13, Debian Jessie's version) with dovecot-lmtp. Here is my /etc/dovecot/conf.d/auth-ldap.conf.ext. I use the static driver for userdb, and the LDAP driver for passdb. passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=mail gid=mail home=/var/mail/%u } Here is my /etc/dovecot/dovecot-ldap.conf.ext file. hosts = localhost ldap_version = 3 dn = cn=dovecot,ou=services,dc=niols,dc=fr dnpass = a-random-password auth_bind = yes base = ou=people,dc=niols,dc=fr pass_filter = (&(objectClass=inetOrgPerson)(mail=%u)) I haven't set the user_filter and user_attrs values, since I thought these would only be usefull for userdb. I haven't set the pass_attrs value, since I don't see why it would be needed (I just need to be able to bind my user, right?). I can't auth_bind_userdn since the e-mail address aren't necessarily related in any way to the user dn. I assumed %u was going to be replaced by the user's full e-mail address. I tried to play a bit with these values to find a working configuration, without success. I tried to search myself on the LDAP server, using the provided dn and dnpass, and I succeeded. I tried to activate debug logs, but that didn't give me much more information (full debug log at the end of this e-mail). I think the problem is that passdb cannot find the user on the LDAP server, but I don't know why. I believe the problem is lying in my non-comprehension of what userdb and passdb actually do. I tried to find out by myself, and I'm here because I didn't manage to do so. I'm sorry if this post looks stupid. Any help and any comments of any kind would be greatly appreciated. Regards, Niols PS: Here is the full debug log that I get after sending a test message to test(a)niols.net (.net vs. .fr: this is not a mistake, I use my .net domain for testing purposes while I use my .fr domain for eveyday life) with swaks: lmtp(3208): Connect from local auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat auth: Debug: LDAP initialization took 0 msecs auth: Debug: master in: USER 1 test(a)niols.net service=lmtp auth: Debug: ldap(test(a)niols.net): passdb doesn't support credential lookups auth: Error: static(test(a)niols.net): passdb doesn't support lookups, can't verify user's existence auth: Debug: userdb out: FAIL 1 lmtp(3208): Error: user test(a)niols.net: Auth USER lookup failed lmtp(3208): Disconnect from local: Successful quit

CentOS RPM updates?
by J Landwehr 30 Mar '16

30 Mar '16

Has CentOS stopped distributing dovecot updates via yum? The current version there is 2.2.10 - which is now over two years old. The link on: http://dovecot.org/download.html <http://dovecot.org/download.html> to “RPMs for Fedora and RHEL/CentOS” http://packages.atrpms.net/dist/el6/dovecot/ <http://packages.atrpms.net/dist/el6/dovecot/> is also broken. Would be great if someone could please point me to alternative locations for authentic RPMs

talloc access after free error ntlmssp_server.c:457
by J Landwehr 30 Mar '16

30 Mar '16

Our new/fresh dovecot imap installation on CentOS (latest from yum repository, which is 2.2.10) is locking up with a panic on a consistent basis and denying service to subsequent clients. The behavior is repeatable. Have spent weeks debugging and trying different configurations with no success. Specific /var/log/maillog error messages are: 12:06:54 dovecot: auth: Error: talloc: access after free error - first free may be at ../auth/ntlmssp/ntlmssp_server.c:457 12:06:54 dovecot: auth: Error: Bad talloc magic value - access after free 12:06:54 dovecot: auth: Error: PANIC (pid 2570): Bad talloc magic value - access after free Our configuration is based on the instructions for NTLM authentication with our Windows 2012R2 AD/Domain server: http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm <http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm> Here are the steps to reproduce: 1. Fresh boot of CentOS server, only configured for postfix/dovecot 2. Connect with Outlook 2016 12.0.4312.1000 32bit on Win7 via IMAP to this dovecot server 3. Any existing and new mail loads in OK to inbox - so authentication is working OK to AD domain server 4. Send an email to someone from Outlook 5. SMTP process completes, message is delivered - 6. dovecot immediately panics on servers, Authentication to dovecot no longer works 7. <systemctl restart dovecot> will hang until a <kill -9> on the “dovecot/auth” PID is performed The issue is with steps 6/7 immediately after 4/5- and is intermittent. Steps 1-3 always work OK, as do 4-5. Further, inbound emails received on this server when no IMAP client is running are always received just fine and dovecot doesn’t hang. Sometimes I have to send a few email messages with steps 4/5 before the issue with 6/7 happens. If I tail -f /var/log/maillog on the server, I can usually determine when 6/7 will fail because there is a line or two with: "dovecot: map: Disconnected: logged out message” being shown, even though the Outlook client is still open. After I see that Outlook closed an IMAP session, even though outlook is still running, I can send a message from Outlook and after it appears in my inbox, dovecot panics/hangs immediately Authentication is otherwise working, e.g. test with: /usr/bin/ntlm_auth —username=alice occasionally takes several seconds to respond, but is usually immediate response is always NT_STATUS_OK: Success (0x0) (I welcome tips to make ntlm_auth always respond more quickly!) I have tried adding lines to smb.conf like: win bind cache time = 300 win bind offline login = true No success I have also looked further into the detailed debugging logs and there is: dovecot: auth: Error: Go user=[alice] domain=[OFFICE] workstation=[pc1] len1=24 len2=290 dovecot: auth: error: login for user [OFFICE]\[alice]@[pc1] failed due to [Wrong Password] dovecot: auth: Error: GENSEC login failed: NT_STATUS_LOGON_FAILURE dovecot: auth: winbind(?,x.x.x.x,<XXX>): user not authetnicated: NT_STATUS_LOGON_FAILURE But I am not sure why there would be that error, since earlier IMAP sessions are working just fine with the same exact domain/username and password. It seems to be something about Outlook quickly opening up new simultaneous IMAP sessions with a CONT command, and NTLM authentication somehow fails with one of them, and panics. It always seems to be when sending an email. Like the process of either receiving a new msg in the inbox and/or also posting the just sent message into the Sent Items folder via IMAP (perhaps when it happens simultaneously, as in a message you cc yourself on) is somehow triggering this. Here is more detailed information that can hopefully help track this down.

Dumb question: dovecot include file
by Jerry 29 Mar '16

29 Mar '16

Dovecot has an include file option. What I am not sure of is why those files use both a *.conf and *.conf.ext extension. I assume both types are included by using the !include <FILE>.conf or !include <FILE>.conf.ext syntax. -- Jerry
